Animal and vegetable fats and oils - Determination of acid value and acidity (ISO 660:2020)

This technical specification outlines the procedures for determining the acid value and acidity of animal and vegetable fats and oils. It establishes standardized methodologies to ensure the accurate measurement of free fatty acids present in these lipid products, which is essential for assessing their quality and purity. The document specifies the use of titration techniques with appropriate indicators and solvents to quantify the acidity levels. By following the defined steps, laboratories can obtain consistent and comparable results across different testing environments. The approach covers the necessary equipment, reagents, and calculation methods required for reliable analysis. This framework supports industries involved in food processing, quality control, and regulatory compliance by providing a unified reference for evaluating fat and oil samples. The method is applicable to a wide range of edible oils and fats, ensuring that manufacturers and regulators can assess product integrity effectively. Adherence to these procedures facilitates trade and safety assessments by maintaining uniformity in analytical results. The specification serves as a practical guide for conducting tests that reveal the condition of fats and oils during production and storage.
